Question

Problem 2: A worker pushes a 1.50 × 10³ N crate from rest with a horizontal force of 345 N a distance of 24.0 m. Assume the coefficient of kinetic friction between the crate and the floor is 0.220. a) How much work is done by the worker on the crate? b) What is the net work done on the crate by ALL applied forces? (draw free body diagram!) c) What is the change in the crate's Kinetic Energy? d) What's the final speed of the crate at the end of the 24.0 m distance?

Step 1

In this case, the force is applied in the same direction as the motion, so θ = 0 and cos θ = 1. Show more…
